ZmMS1 coordinates ROS homeostasis, lipid allocation, and male fertility for maize breeding applications

Journal of Integrative Plant Biology, EarlyView.
The redox‐sensitive transcriptional repressor ZmMS1 coordinates reactive oxygen species homeostasis and lipid allocation for pollen exine and anther cuticle formation. Loss or precocious expression of ZmMS1 causes male sterility. Constitutive overexpression induces dwarfism and semi‐sterility. These findings enable flexible maize male‐sterility systems

Anther culture properties of oat x wild red oat progenies and a search for RAPD markers associated with anther culture ability

Agricultural and Food Science, 2008
A study was carried out to improve anther culture ability of the non-responsive cultivated oat, Avena sativa L. cv. Puhti by introgressing favourable alleles from the responsive wild red oat, Avena sterilis L. acc. CAV 2648.

ATXR5 and ATXR6 restrict meiotic crossover formation within heterochromatin in Arabidopsis

Journal of Integrative Plant Biology, EarlyView.
The Arabidopsis H3K27 mono‐methyltransferases ATXR5 and ATXR6 repress crossovers within meiotic heterochromatin, are required for heterochromatin condensation and H3K27me1 establishment, and specifically influence the maintenance of DNA methylation in meiocytes.

A robust biotechnology induces artificial genomic duplication via transient RNAi‐mediated suppression of OSD1 in rice

Journal of Integrative Plant Biology, EarlyView.
Plant Polyploidization via Gene Interference, a robust technology for inducing polyploidy in various rice accessions, uses transient RNAi‐mediated suppression of OSD1 to induce genomic duplication. Two strategies were used to directly induce fertile autotetraploid plants in the first generation, thereby substantially shortening the breeding cycle ...

Mutations in SUMO conjugating enzyme reveal contributions of sumoylation to plant stress resilience and yield

New Phytologist, EarlyView.
Mutations in small ubiquitin‐related modifier (SUMO) conjugating enzyme that increase or decrease functionality reveal SUMO contributions to growth and stress resilience. Summary Small ubiquitin‐related modifier (SUMO) conjugation is a fundamental process in all metazoa, with multiple roles in development and stress responses.
